Variety of Calla Lily Named &#39;PACO&#39;

ABSTRACT

‘Paco’ is a new variety of  calla  lily having flowers with a purple-colored spathe that produces 2-15 flowers per tuber. The flower stems are about 50 cm. in height and the leaves are green with a few whitish spots and have a leathery texture.

BOTANICAL CLASSIFICATION

Zantedeschia sprengeri

VARIETAL DENOMINATION

‘PACO’

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of calla lily, botanically known as Zantedeschia sprengeri and hereinafter referred to by the cultivar name ‘Paco’.

‘Paco’ is a product of a planned breeding program which had the objective of creating Zantedeschia hybrids for pot flower production in a wide range of colors with a large, classic flower shape. The breeding program began in 1989 and the new cultivar is a seedling selected from the crossing of Zantedeschia sprengeri seedling C02029 (male parent, unpatented) with an unnamed Zantedeschia sprengeri rehmanii selection (female parent, unpatented). ‘Paco’ was selected in 2004 by the inventor C. J. J. Randag in 't Zand, The Netherlands as one flowering plant within the progeny of the stated cross.

The first act of asexual reproduction of ‘Paco’ by tissue culture was performed by the inventor in August of 2005 in 't Zand, The Netherlands. Further asexual reproductions by tissue culture at the same location has demonstrated that the combination of characteristics as herein disclosed for the new cultivar are retained and reproduced true to type through successive generations of asexual reproduction.

The following observations, measurements and comparisons describe plants grown in 14 cm. pots in 't Zand, The Netherlands under greenhouse conditions which approximate those generally used in horticultural practice. Color references are made to the R.H.S. Colour Chart of The Royal Horticulture Society of London, except where general color terms of ordinary significance are used.

The present invention has not been evaluated under all possible environmental conditions. The phenotype may vary with variation in environment without a change in the genotype of the plant.

The following traits have been repeatedly observed and determined to basic characteristics of ‘Paco’ which, in combination, distinguish this calla lily as a new and distinct cultivar:

1. Purple-colored spathe;

2. Fast forcing time; and

3. High flower production.
